Luziwen – MQ-3 Alcohol Gas Sensor Detector Module – STSX0177

The MQ-3 Gas Sensor Module is designed for detecting alcohol, ethanol, and smoke concentrations in the air. It provides excellent sensitivity, fast response time, and high stability, making it ideal for applications such as breath analyzers, air quality monitors, and safety detection systems. The module operates on a 5V power supply and offers both analog and digital outputs, enabling integration with various microcontroller platforms. The sensor uses a metal-oxide semiconductor to detect gas concentrations, and its onboard potentiometer allows for easy calibration of the detection threshold. This module is a cost-effective solution for projects that require reliable alcohol or smoke detection.
